lII L-GEOSEHIQG SIGNAL.

Serial No. 189,5?0.

Fig. 8 is a detail, sectional view taken on the line 88 of Fig. 7.

Fig. 9 is an elevation of the trouble signal.

I have used the refcrcnce character 10 to indicate generally the l'iighway crossed by :1 railway track coin ilrising the tics ll and lhc right and loft rails l2 and 13, (when the track is viewed in the direction as in Fig. l).

A semaphore post is mounted at a dismncc from the track and near the side of the highway and at its uppcr cnd carries a casing 15, in which is journallcd a shaft 16, which extends outwardly through the casing and has secured to its outer endn' SCIllZlr' phore arm 1?.

The semaphore arm 17 has :1 rod Winningoisc l8 at one end and its shorter end is curved as at 19 and provided. with a weight 20. It may now he noted that 21s the arm is swung upwardly to its signalling position iBl in the direction indicated by the a row :22, that the weight will oppose this upward swinging until the arm has reached 21.1)Osiii011 approximately of 4:5 and from that point the Weight 20 will aid the upward swinging of the semaphore arm. The object of thus arranging the weight 20 is to provide means ior maintaining the semaphore arm in a vertical, depending position against the action of the wind or any accidental displacement from this position end if) help maintain the arm in it's horizonmli y extended position 2i so that the mechanism, which will later he described, for raising the min will he Portia d g relieved of the weight the arm during the tune thzrt it remains in horizontal poeiiion. Since this mechanism includes a resilient spring ii. is

important that the spring be relieved oi tension as much as possible. pi note as a stop for the semaphore nun in lepending position and a pin 2% eimileriy aches no 1-; stop for the semaphore in onion ed posiion.

The trip lever in each iosi'ance comprises a lever ca Tl. formed integrally u'iili a A. $2. The lever ionising ii is in shape so as to allow lhe lever I e which pivoted at H in the lower por 1.: oi lire housing, to more from the posii lie so. inclined position Where prceciicu 70 may pass orer the upper lb, er. Covers 5 and '75 are lever. The covers prevent iccuinularing Within the lever lionsin the lever slides forwardly, the covers slide also. The lever is formed in Euro sections, the upper section Y3 being 31 hinged at; to the lower section 723, and a linger W. formed integrally with the upper sectionv i -5 below the hinge to prevent increment or the section 7'3" beyond the 'gned position relative to the lower section shown in, *2 A. spring 75% serves to u iza'u sections in these relative posiconnected "lo lhe lingers '7? and is lower section l3 shown.

Ordinarily the sliding of the pawl all forwardly will bring the pin S-l to a position Where, when the lrig er raises the pin, it Will not curry-e the lip 80.

lo addition to the Warning given by the semaphore arm, ll provide a Warning bell 90, mounted "within the casing 15, actuated by a source of current, which is not shown, the circuit being made and broken by a switch poiru'; 91 on the lever 25, engaging a brush 92 for grounding the bell circuit when the semaphore arm is raised. The spring 26 serves not only to allow slow movement of the semaphore arm to its raised position, but also to keep the transmitting cable taut at all limes. This is important since any slack in the able would cause a jerk, tench ing to break it under the strain lHlPOSQd. by the quiclr blow of a passing li'aiu.

Home changes may be made in the coustrucr-ion. and arrangement of the parts of ii; 15 my intention to cover by my claims,

any modified forms of structure or use of mechanical equivalents, which may be reasonably included Within their scope.

I claim as my invention:
